That same maneuverability also broke the stalemate at Omaha Beach.
I read where one GI on shore used a WWI signal lamp and acted as a forward observer for the DDs - one of them Polish. Some got in so close their hulls were scraping bottom.
One vid on YouTube showed a large hole in a German casement (direct hit) and by triangulation, were able to identify the DD who fired that killer shot.
They really did save the day.
